Royal MCP

Run your WordPress site from Claude, ChatGPT or any AI app: write and edit content, manage your store, fix SEO and undo any change. Works alongside Elementor's and WooCommerce's own MCP tools. 100% self-hosted.

Royal MCP is an open-source WordPress plugin that turns your site into a Model Context Protocol server. Connect it once, and your AI app can read and change your site the way you would from wp-admin: posts, pages, media, menus, your WooCommerce store, Elementor and Divi pages, SEO, backups and security. Every call runs as a WordPress user, is checked against that user's capabilities, and lands in an activity log, and every destructive change can be undone.

Nothing is relayed through a third-party service. Your API keys, sign-in tokens and logs stay in your own WordPress database.

What you can do with it

Ask in plain language. These all work on the free plugin:

Built to work alongside other MCP tools

Royal MCP is designed to run next to the MCP tools other plugins ship, so your AI can reach for the best tool for each part of a job.

• Elementor. When Elementor's own MCP is switched on, Royal MCP detects it and tells your AI that Elementor's builder is there for designing new layouts. Royal MCP's Elementor tools keep handling edits to the pages you already have: text and image swaps, widgets, cloning and templates.

• WooCommerce. WooCommerce's own MCP abilities keep working. Royal MCP adds the rest of the store: coupons, variations, attributes, customers and store stats.

• WordPress Abilities API. Royal MCP's tools also register as WordPress abilities. With the MCP Adapter installed they are served on Royal MCP's own adapter server, royal-mcp-server, with the same permission checks, switches and logging as the native endpoint.

Royal MCP answers on its own endpoint and never switches off another plugin's tools, so together they cover more of your site than any one of them alone.

Safety

• Your AI app asks first. Claude, ChatGPT and other clients ask you to approve each destructive tool call by default.

• Drafts first. New posts and pages start as drafts.

• Read-only and drafts-only modes. One switch refuses every tool that changes the site, or every tool that would publish.

• An access level per connection. Give each connected AI app Full, Read-only or Drafts-only access from the Connected Clients screen, and revoke any of them.

• Recent Changes with undo. Every destructive write stores a snapshot first. The Recent Changes screen shows the before, after and current values, and one mcp_undo_last_operation call reverses a change within 72 hours.

• Activity log. Every tool call is logged with the tool name, argument keys, IP and user agent. Argument values are never stored.

• Dry runs. High-impact writes such as site options and permalink structure can be previewed before they are applied.

Capabilities

270 tools: 113 core tools that are always available, plus 157 integration tools that load only when the matching plugin is active.

Plugin integrations (157 tools)

Not seeing your plugin? The core tools still cover posts on any custom post type, any plugin's custom fields through post meta, and any plugin's comments. Request an integration on the WordPress.org support forum. If you build that plugin, you can add its tools to Royal MCP yourself or partner with us.

Config file: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows).

Cursor, VS Code, Claude Code and other MCP clients

Add an HTTP MCP server with your MCP Server URL and an Authorization header set to Bearer YOUR_API_KEY, or use OAuth where the client supports it.

Raw HTTP

# 1. Start a session. -i prints the headers so you can copy Mcp-Session-Id.
curl -i -X POST https://yoursite.com/wp-json/royal-mcp/v1/mcp \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{
    "jsonrpc": "2.0",
    "method": "initialize",
    "id": 1,
    "params": {
      "protocolVersion": "2025-11-25",
      "capabilities": {},
      "clientInfo": {"name": "my-app", "version": "1.0"}
    }
  }'

# 2. List the tools, using the session id from the response headers.
curl -X POST https://yoursite.com/wp-json/royal-mcp/v1/mcp \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Mcp-Session-Id: <session_id>" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc": "2.0", "method": "tools/list", "id": 2}'

The older X-Royal-MCP-API-Key header still works in this release but is deprecated. Send the key as Authorization: Bearer instead.

Scope

What Royal MCP deliberately does not do:

• No core file changes. It never writes to wp-content/themes, wp-includes or wp-admin.

• No plugin installs or upgrades. It can list plugins, not install, activate or update them.

• No raw SQL. Every query goes through WordPress APIs and prepared statements.

• No Elementor Theme Builder templates in the free plugin. Theme Builder work is in Royal MCP Pro.

• No Beaver Builder or Bricks layout JSON writes. Their standard post content is readable and writable; builder-specific layout data is left alone unless a dedicated tool covers it.

Royal MCP works with the rest of the Royal Plugins family. Each one adds its own tools to Royal MCP when it's active.
